Description

[Detailed description of the invention] This invention relates to a block for supporting the workpiece when drilling holes in round bars, square bars, or plates. To provide a block that can freely adjust the size of a holding part to support a workpiece in a stable state regardless of its size, and that can be used not only as a workpiece holding block but also as a V-block for warping. It's about doing.

Traditionally, when drilling with a drilling machine, the workpiece was held in a vise fixed on a table.
It gets stuck in the vise and the work to remove it is complicated.
If you are skilled, you can place a V-block on the table without using a vise, and place the workpiece in the V-groove to perform machining.

However, it is necessary to use different large and small blocks depending on the thickness of the workpiece, and since conventional V-blocks are made of cast metal, they have the drawback of damaging the V-groove with a drill during machining.

Therefore, this invention was devised to eliminate the above-mentioned drawbacks of the conventional technology, and an example will be explained below with reference to the drawings.
A pair of square blocks 3 and 4 are formed by flattening a part of a round bar over the entire length and forming a pair of square blocks on a guide shaft 1 in which a key 2 is embedded.
are slidably fitted without rotation, and both blocks 3,
A tightening screw 5 corresponding to the guide shaft 1 is screwed into 4 so that each block 3.4 can be fixed at a predetermined position on the guide shaft 10. , slopes 6 and 1 are provided symmetrically so that a V-groove is formed when both blocks 3 and 4 butt each other, and both blocks 3 and 4 are provided symmetrically.
Stepped grooves 8 and 9 are formed at the upper corners of the surface opposite to the surface having the inclined surfaces 6 and 7, and furthermore, a female threaded hole 10 is formed on the bottom surface of both blocks 3 and 4. , pins 11.12 are installed on the side surface of one block 3 and on the top surface of the other block 4, respectively, and a stopper 13 made of a strip plate is attached to each pin 11.12.
．． 14 with the tightening screw 15, and fix the fixing position with the pin 11.
It is provided so that it can be adjusted along 12.

This invention has the above-mentioned structure, and when drilling a round bar workpiece 16, as shown in FIG. After screwing into the hole 10 and fixing the block 3, the other block 4 is fixed to the table 11 with bolts in the same manner as described above at a position appropriately separated from the block 3 depending on the thickness of the workpiece 16. .

The rain block 4 is also fastened to the guide shaft 1, and both blocks 3 and 4 are set so that the drill 18 is located at the center of both blocks 3 and 4.

Then, drilling is carried out by placing the workpiece 16 between the opposing inclined surfaces 6 and 7. At this time, the stopper 13 on the side surface of the block 3 is set with the required dimension from the center line of the drill 18, When loading the workpiece 16, the workpiece 16
By placing the tip of the hole in contact with the stopper 13, a hole can be immediately drilled at a predetermined position without marking the workpiece 16 one by one.

In addition, when the processed material is a square material or a flat plate, both blocks 3
, 4 are replaced so that the stepped grooves 8 and 9 face each other, and the workpiece 19 is placed between both grooves 8 and 9, and the stopper 14 on the upper surface of the block 4 is placed on the workpiece 19. After pressing the top surface, Komei processes it.

The stopper 14 serves to stabilize the workpiece 190 when the drill 18 is removed from the workpiece 19.

Furthermore, the block according to this invention can be used as a V block for warping, in which case both blocks 3 and 4 are placed on a surface plate, and one block 4 is attached to the guide shaft 1.
The distance between the block 3 and the other block 3 is adjusted according to the thickness of the workpiece, and the adjusted block 4 is also fastened to the guide shaft 1, and the burr work is performed in the same manner as in the past.

As mentioned above, if you use the block invented by this invention,
The fixing position can be adjusted appropriately along a pair of block guide shafts with inclined surfaces and stepped grooves.
Large and small workpieces can be stably supported by the individual workpiece holding blocks, there is no risk of damage to each inclined surface with a cutter such as a drill, and the work efficiency can be increased by the casing and each stopper. It has the following effects.
